Biopsy wound closure device

摘要

A closure device for performing a routine biopsy procedure without the use of sutures or butterfly bandages. The method and closure device controls bleeding, repairs the biopsy site, reduces the likelihood of inducing excessive scarring and reduces the handling of tissue. The closure device is comprised of a circular sponge made from an absorbable foam material which swells and fills up the defect left by biopsy and an applicator for implanting the sponge into the biopsy site. The sponge is pre-cut to a diameter which approximately corresponds to the diameter of the punch which is used for excising a biopsy specimen. A fibrous cotton wad is attached to the other end of the applicator. After the specimen is excised the sponge is implanted into the space from which the specimen was taken. A slight pressure is applied to the sponge with the fibrous cotton wad for approximately 30 to 60 seconds to stop any excess bleeding.
